Book ELABORATION PAR ELECTRODEPOSITION DE MULTICOUCHES CUIVRE COBALT  CARACTERISATION STRUCTURALE ET MAGNETIQUE

Download or read book ELABORATION PAR ELECTRODEPOSITION DE MULTICOUCHES CUIVRE COBALT CARACTERISATION STRUCTURALE ET MAGNETIQUE written by PASCALE.. NALLET and published by . This book was released on 1997 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL DE THESE EST CONSACRE A L'ETUDE DE MULTICOUCHES CUIVRE-COBALT ELECTRODEPOSEES A PARTIR D'UN ELECTROLYTE UNIQUE. NOUS AVONS DETERMINE LES CONDITIONS DE PREPARATION DE CES MULTICOUCHES PAR LA TECHNIQUE DES POTENTIELS PULSES. UN PILOTAGE PAR MICROORDINATEUR PERMET UN CONTROLE DES QUANTITES D'ELECTRICITE UTILISEES ET AINSI UNE MAITRISE DES EPAISSEURS INDIVIDUELLES DES COUCHES. L'UTILISATION D'UNE MICROBALANCE ELECTROCHIMIQUE A CRISTAL DE QUARTZ PERMET DE CARACTERISER LES MASSES REELLEMENT DEPOSEES. NOUS AVONS ELABORE ET ETUDIE DES MULTICOUCHES DONT LES EPAISSEURS NOMINATIVES DE CUIVRE ET DE COBALT SONT REGULIERES ET, DES SYSTEMES POUR LESQUELLES CES MEMES EPAISSEURS REPONDENT A UN ALGORITHME MATHEMATIQUE. LA CARACTERISATION STRUCTURALE NOUS A PERMIS DE MONTRER QUE NOS MULTICOUCHES ONT UNE STRUCTURE CRISTALLINE CUBIQUE A FACES CENTREES (AVEC UN PARAMETRE UNIQUE INTERMEDIAIRE ENTRE CELUI DU CUIVRE ET DU COBALT C.F.C.). NOUS AVONS MONTRE, A L'AIDE DE LA MICROSCOPIE EN TRANSMISSION, UNE EXCELLENTE REGULARITE DES COUCHES. LA LARGEUR D'INTERFACE (CALCULEE PAR LA TECHNIQUE DES FRANGES DE FRESNEL) EST DE 0,53 NM, ELLE EST COMPARABLE A CELLE OBTENUE POUR DES MULTICOUCHES ELABOREES PAR VOIES PHYSIQUES. LA PRESENCE D'HYDROGENE DANS LA MULTICOUCHE A ETE CARACTERISEE PAR PLUSIEURS TECHNIQUES COMPLEMENTAIRES. LES MESURES D'AIMANTATION ONT MIS EN EVIDENCE UN COMPORTEMENT DE TYPE FERROMAGNETIQUE. NOUS AVONS MONTRE QUE NOS MULTICOUCHES SONT BIEN DEFINIES A PARTIR D'EPAISSEURS NOMINATIVES DE COBALT DE 2 NM. UNE ETUDE DES PROPRIETES DE MAGNETORESISTANCE NOUS A PERMIS DE TROUVER LES CONDITIONS D'ELABORATION PERMETTANT D'OBTENIR UNE MAGNETORESISTANCE GEANTE (DE 5 A 10%) SYSTEMATIQUE.
